- French telephone. If you look for old phones on eBay, you will see a lot of telephones described by their American owners as "French" telephones that turn out to be nothing of the sort, just standard American handset telephones. Why is this? Americans, or at least older Americans, tag any handset phone as 'French'. The reason is that until the 1920s handset telephones were exceedingly uncommon in the USA. In fact they turned up mainly on imported instruments and although an American firm sold handset phones under the 'Grabaphone' banner, these were not used on the public network. One of the sights that made a deep impression on American soldiers who went to fight in France during the Great War was telephones with handsets. They had simply never seen these before and when they returned home they termed all handset telephones "French". The nickname has remained to this day.
